Evaluation of a tibial torsiometer applicable to clinical practice

This study evaluated a new tibial torsiometer that is universally applicable to all limb sizes and requires no special training, jigs, or radiographic equipment. To compare the reliability of measurements obtained with the torsiometer, 160 tibias were evaluated with both the torsiometer and computed tomography. Results for both methods were identical in 51 tibias, within 1 degrees in 66 tibias, and within 2 degrees in 43 tibias. The difference between the two methods was not significantly different. No significant difference was found among testers. This device should prove to be useful for the quantitation of tibial torsion.
